Facebook has suspended another data analysis firm for violating its policies in the wake of a scandal that alleges millions of users' personal information was misused.

Data analytics firm CubeYou, which collected information about users through personality quizzes, was suspended Sunday for misleadingly labeling its product as "for non-profit academic research" and then sharing the information with marketers, Facebook said, confirming a report by CNBC.

"These are serious claims and we have suspended CubeYou from Facebook while we investigate them. If they refuse or fail our audit, their apps will be banned from Facebook," Ime Archibong, Facebook vice president of product partnerships, said in a statement that thanked CNBC for bringing the matter to the social networking giant's attention.

"In addition, we will work with the UK ICO [Information Commissioner's Office] to ask the University of Cambridge about the development of apps in general by its Psychometrics Centre given this case and the misuse by Kogan," Archibong said, referring to Cambridge lecturer Aleksandr Kogan.

Facebook has accused Kogan of collecting the data legitimately through a personality quiz app but then violating Facebook's terms by sharing the information with Cambridge Analytica, a firm hired by the Trump presidential campaign during the 2016 US election.

Cambridge Analytica, for its part, has said through a series of statements that the allegations against it are incorrect and that it acted appropriately.

Facebook said it's auditing records in an effort to find any other companies that may have taken advantage of its service.

"As we find more Cambridge Analyticas, we're going to find a comprehensive way to put them out and make sure people see them," Facebook Chief Operating Officer Sheryl Sandberg told BuzzFeed in an interview published Thursday, referring to efforts to publicize problems.
